Embodiment Construction

[0038] The present invention will be further described below in conjunction with the accompanying drawings.

[0039] refer to figure 1 , all drones in the drone network need to pre-store block 0 (initial block), the specific instructions are as follows:

[0040] Block 0 contains the hash value Hash of the block 0 and the certificates of all drones in the drone network 1 -cert N , where N represents the number of drones in the network, and the hash value Hash 0 The calculation method is as follows:

[0041] Hash 0 =SHA_256(cert 1 ,cert 2 ,...,cert N ),

[0042] Among them, SHA_256() is a secure hash algorithm function.

[0043] refer to figure 2 , the specific implementation steps of the present invention are as follows:

[0044] Step 1, when a UAV node finds a suspicious target during the mission, it can initiate group decision-making.

[0045]When the drone finds a suspicious target, it initiates two voting transactions, namely decision x001 and decision x002, a...

Abstract

The invention discloses a blockchain-based unmanned aerial vehicle (UAV) group decision-making method. According to the scheme of the invention, in the process of performing a task, as the ability ofa single UAV to obtain information is limited, the overall environmental perception capability is not strong; therefore, with the cooperative control of multiple UAVs, decision-making and consensus mechanisms for tasks and targets can be achieved. When a UAV node finds a suspicious target during the task, a group decision can be initiated, the remaining UAVs gather around the target, voting is performed according to collected information, and voting results and the collected information are simultaneously written into a blockchain to provide a transparent, secure and traceable group decision-making process and reach a consensus. On the other hand, according to historical information in the blockchain, the authenticity of data collected by the UAVs can be identified, and the validity of theinformation interaction within a UAV network can be ensured.

Description

technical field [0001] The invention relates to the field of UAV network collaborative control, in particular to a blockchain-based UAV group decision-making method. Background technique [0002] Unmanned aerial vehicles (UAVs) have been widely used in many fields such as military, search and rescue, and reconnaissance. They have the characteristics of low cost, convenient operation, flexibility and reliability, and can selectively and targetedly observe ground targets at close range to improve the reliability of intelligence sex and timeliness. At present, in an increasingly complex task environment, a single UAV cannot complete heavy and complex tasks due to constraints such as payload and flight time. Therefore, the use of multi-UAV cooperation to achieve tasks such as target search, target strike, and defense has gradually become a research hotspot. A networked UAV swarm can greatly expand the application range and mission of UAVs. [0003] However, since the UAV netwo...
